NSO 4.7 upgrade to 5.7

[caramir2]

Hi Guys

There is a documentation or procedure to upgrade NSO from 4.7.7.1 to 5.7.1.1, I will work with a customer with this requirement.

Thanks in advanced

There are 2 files in the NSO documentation that you should to look at. First, the nso_installation_guide covers the standard procedure for upgrading NSO. However, from NSO 5.1 onwards, NSO implements the Common Device Model, or CDM. As a result, you must perform the CDM migration procedure instead of the standard upgrade procedure when upgrading from NSO 4.7 to NSO 5.7.1.1. The details for the migration are contained in the nso_cdm_migration_guide. I recommend reading the migration guide thoroughly before performing the upgrade.
